The normalization factors are ||ePM|| = 5.02 rad, ||eVM|| = 7.05 rad/s and ||eAM|| = 61.5 rad/s2 for position, velocity and acceleration errors, respectively. The errors are evaluated at the via-point (k = v) and at the final point k = T. The expressions pos, vel, and acc identify position, velocity, and acceleration constraints, respectively.
